RFC 1983 states that “dotted-decimal notation... refers [to] IPv4 addresses of the form A.B.C.D; where each letter represents, in decimal, one byte of a four-byte IPv4 address.” In other words, the dotted-decimal notation separates four decimal byte values by the dot, or period, character (‘.’). Each decimal value represents one byte of the IPv4 address starting with the most significant byte in network order.
